RICHARD GRAINGER NAS H, OF LUCAN, NEAR DUBLIN, IRELAND.

MACHINE FOR WASHING BOTTLES.

Specification of Letters.Patent.

Patented May 21, 1907.

Application filed May 1 1, 1906. Serial No. 316,704.

To all whom, it may concern;

Be it known that I, RIcHARn GRAINGER NASH, of Finnstown House, Lucan, near Dublin, Ireland, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Machines for Washing Bottles, Crooks, and the Like, of which the following is a specification.

This invention relates to machines adapted for the simultaneous washing and thorough cleansing of a number of bottles, crocks or the like, both internally and externally, the action of the various parts instrumental in the several operations being automatic.

In the accompanying drawings, which illus trate a washing machine constructed according to my invention, Figure 1 is a face view of the apparatus, Fig. 2 a side elevation and Fig. 8 a horizontal section on the line a;9c in Fig. 1. Figs. 4, 5 and 6 illustrate respectively in vertical section, face view and plan, the means for cleaning the interior and exterior of the bottle. Fig. 7 illustrates in side elevation the means for rinsing the bottle, while Fig. 8 is a plan of the means for feeding the bottle to its carrier and finally ejecting it therefrom.

In carrying out my invention as applied, by way of example, to the cleansing of bottles, I mount a series of bottle-carriers a upon a ring A supported upon a roller 0 and brackets a a mounted upon the tank B. The periphery of the ring A is formedwith a series of notches 6L3 adapted to be engaged by projections a a formed upon the peripheryof a disk A, which is driven from the main shaft C of the machine by suitable gearing such as the bevel wheels 0 c driven by the worm c and worm-wheel 0 The disk A gears with the ring A in such a manner that the projections thereon successively engage the notches in the ring and intermittently rotate the lat ter.

The disk A which rotates the ring A also serves to operate means for feeding the bottles to be cleansed to the carriers, and means for discharging them from the carriers, subsequently to the cleansing operation. For this purpose, I employ a horizontally disposed arm D connected at its one end to a slide cl, mounted on a guide bar (1 and connected to a pivotally mounted lever 612 reciprocated by the disk A, while its opposite end is furnished with means for feeding the bot- .tles to the machine and for ejecting them after being cleansed. For feeding the bottles to the machine, the extremity of the arm D is provided with a crank E arranged above an inclined chute e and supported by the guide bar d. The dirty bottles are carried upon the chute, preferably on their side, and are normally supported by one arm a of the crank but as the arm D is moved forward, as the result of vibratory movement imparted to the lever d the leading bottle of the row is disengaged from the crank-arm e and rolls or slides into position opposite its carrier where it is supported by an arm 6 proj ecting laterally from the crank E. During the return movement of the horizontal arm D, the crank engages the bottom of the bottle and ,pushes it into its carrier. For ejecting the bottle after being cleansed, a plunger F arranged co-axially with the bottle maybe connected to the horizontal arm D by means of the rod f, so that, during the forward movement of the latter, the plunger F will eject the bottle from the carrier 011 to a chute f.

Each bottle, while in its carrier, is free to move in an axial direction; and duringthe first part of its journey round the axis of the ring, the bottom of the bottle is supported upon a platform 1) within the tank B; while during the remainder of its journey, the neck is supported upon a hoop Z) angular in crosssection, the bottle being supported between the sides of the angle.

The bottles, during the first half of their journey round the axis of the ring A, pass through the water in the tank B. lVhile immersed in the water, the bottom of the bottle may be cleaned by means of a brush mounted upon the platform 6. After each bottle has traversed about 180 it arrives op posite a set of brushes G, 9, (see Fig. 4) which are revolved, within a casing G by suitable gearing, from the main shaft C, and which are adapted for cleaning both the interior and the exterior of the bottle. When the bottle is in this position, a plunger 9, mounted on the slide (Z connected to the horizontal arm D engages the bottom of the bottle, and, during the forward movement of the arm, pushes the bottle through the carrier a into engagement with a bell-crank 9 mounted on a slide which is connected to the slide (1 by a spring 9 By means of this spring the bottie is firmly held as it passes over the internal brush g and through the external brush G and while undergoing the brushing operation.

The arm g of the bell-crank is hollow and formed with a bell-mouth which serves to center the bottle; the latter being guided to the arm by a lever g pivotally mounted on. a frame 9 supported upon the casing G". For the purpose of guiding bottles of unequal diameter, one arm (9 of the lever g is curved longitudinally, while in cross-section one of its sides is formed at such an angle as to be in the same plane as the surface of the bell-mouth. The frame g is formed with. a projection g" which serves, as the ring A rotates, to guard against the necks of the bottles fouling the under side of the lever g. \Vhile the bottle is passing to the brushes G g, the lever 9, one arm of which is held by a projection 9 formed on the slide g, is released from the neck of the bottle, thus permitting the free passage of the body of the bottle. On the return movement of the slide g the projection g re-engages the lever g and raises it into operative position, as shown in Fig. 5.

The bottle, having been scarified by the revolving brushes, is returned to the carrier by means of the spring-controlled slide 9 ready for the next operation, which consists in rinsing the bottles. For this purpose, I provide a nozzle H mounted on the frame of the tank and in communication with a suitable water supply it. This nozzle is so disposed as to be co-axial with the mouth of the bottle when the latter has moved to an. approximately vertical position. Then the bottle is co-aXial with the nozzle, it may operate a lever in connection with the spindle h of a water-supply valve 7L and admit water to the bottle; and when the bottle moves away from the nozzle, the supply of water is cut off. But I prefer to operate the water-supply valve 7L2 by a lever 725 which is supported upon a cam h mounted upon the horizontal arm D. As this arm is'reciprocated, the spindle 7r opens the valve 72 and admits a jet of water into the bottle. At the same time water may be sprayed over the bottle by way of the pipe 72?. To insure bottles of varying sizes being placed coaxial with the nozzle H,

the ring 7/ is provided with a projection 6 formed with a convex surface over which the mouth of the bottle rides and slides into position. The bottle having been rinsed, its circumferential journey around the axis of the machine is completed, during which pe-' riod it may be dried or sterilized. It ultimately arrives in position opposite the plunger F, by means of which it is ejected from the carrier in the manner previously described.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a bottle-washing machine, the combination, with a ring furnished with a series of bottle-carriers, of means for pushing the bottles out of their carriers internal and external revolving brushes mounted. in station ary bearings and adapted to receive said ass rare bottles,'and means for returning the bottles to their carriers, arranged or operating sul stantiallyas herein described.

2. In a bottle-washing machine, the eombination, with a ring, furnished with a series of bottle-carriers, of a scarifier a reciproeable arm provided with means for supplying each carrier successively with a bottle with means for introducing the bottle to said scari'lier, whereby it is cleansed both il'ltelllztlf and externally, and with means for finally ejeeling the bottle from its carrier, substantialh as set forth.

3. In a bottle-washing machine, the combination, with a ring furnished with a series of bottlecarriers, of a brush for cleaning the interior of the bottle of a pair of slides eonnected by a spring, a pusher carried by one slide and adapted to engage with the holtoms of the bottles, and a hollow arm earried by the other slide, such arm surr umding the said brush and being provided with a bellmouth, suitable for engaging with the mouth of the bottle, substantially as herein de scribed.

4. In a bottle-washing machine of the general character herein referred to, the combination, with the bottle-carrier, of a reciprocating arm furnished with a crank and a chute, arranged beneath said crank and serving to support the bottles to he eleansed. substantially as set forth.
